Introduction
It is possible to configure charts for the collection execution in characteristics of the variable and attribute types.
This configuration allows defining the number of rows and columns in which the screen will be divided, as well as the charts that will be displayed on each space.
To do so, first, it is necessary to know the rules to enable each chart divided into variable and attribute rules. See the table below for further details:
Rules to enable each chart
The variable characteristic charts have the following rules to be displayed:
Evaluation ranges: In the characteristic, it is necessary to have at least one evaluation range configured and one reading that fits into the range.
Average and range: The characteristic must be configured with two or more readings and have at least two entered samples.
Individual value and moving range: The characteristic must be configured with a reading and have at least two entered samples.
Average and standard deviation: The characteristic must be configured with two or more readings and have at least two entered samples.
Stoplight chart: The characteristic must be configured with at least one evaluation range and have at least two entered samples.
Histogram: It is necessary to have at least two entered samples and the standard deviation must be different from zero.
Box-plot chart: It is necessary to have at least two entered samples.
The attribute characteristic charts have the following rules to be displayed:
P chart: To use the P chart, it is necessary to have at least two entered samples. This chart evaluates the defective fraction, represented by the number of defective items divided by the total quantity of that sample.
Np chart: It is necessary to have at least two entered samples to use the Np chart. This chart registers the number of defective items in each sample.
C chart: To use the C chart, it is necessary to have at least two entered samples. This chart registers the number of defects in each sample.
U chart: It is necessary to have at least two entered samples to use the U chart. This chart evaluates the number of defects per unit.
Pareto of defects: In the Pareto of defects, it is necessary to configure at least one defect for the characteristic being analyzed. Moreover, it is necessary to have at least two entered samples in which the defect is recorded.
In this case, it is possible to configure both a chart for all system collections and a specific chart for a certain collection.
Refer to the articles below to see each case:
- Configuring an execution chart for all collections.
- Configuring an execution chart for a single collection.
